The power mosfets will trigg with spwm signal which is made by compared sine wave and triangle waves. 1 Note that the output of each pulse-width modulator drives one leg of the inverter only in a complementary manner. 5 Unipolar SPWM for H-bridge voltage source inverter 41 Figure 3. It works correctly, but But there's one little problem: I have pure sine wave only when the load on the output of my inverter is greater than 300W. wave boundary.
